The new Backtrack 4 beta is out!, you can download your ISO here, also you can check the backtrack 4 info on their blog.

The most interesting feature is that is based on Ubuntu, this mean that will be easy to update, maintain, create packages, etc! The Backtrack team wants that besides of being your live CD, to be your every day desktop, and with this change i think that a lot of users will make the change.

Another feature is the support for pyrit and CUDA, to exploit the power of the GPU's.
